- About CDI
We have a number of innovative Ground Floor solutions that can be used in either new-build or renovations.
These include the FastSlab ground floor for replacing rotten suspended timber floors with an insulated, light weight screeded ground floor often incorporating underfloor heating, we also have the insulated Op-Deck system for high loads, large spans and cantilevers that includes an optimised concrete T-beam floor design.
Ground floor solutions are always worth discussing to ensure that they fit with the project and the conditions of the proposed site or design.
This should be done as soon as possible within the detailed design phase of the project to give the best chance of success. We are always happy to provide our guidance as to whether our systems are suitable or not and if they add to the project.

Q
What are the Lewis Deck sheet sizes?
AQ: What sheet sizes are held in stock for delivery within a few days after order? A: We stock 2500mm and 1300mm sheets. These are all 630mm wide and 16mm deep. Deliveries are made via the pallet network directly to site. The smaller sheets are aimed at small bathroom renovation projects and can be supplied in small numbers via TNT. 2.5* and 1.3m sheets allow for the 100mm overlap to occur over a joist, with joist centres being either 300mm, 400mm, 600mm, 800mm*, 1200mm and 2400mm*. (*2.5m sheet only) For larger projects we are able to produce bespoke sheet sizes if required, please get in contact to discuss other options for sheet sizes.

Q
Why don't my Lewis sheets interlock like they do in the video?
AQ: Why don't my sheets interlock like they do in the video? A: The sheets have two sides (one printed, one plain), the dovetails on either side are different widths, it is then necessary to alternate the sheets print up and then print down.
QIs this a question?
AIf it is, this is an answer.
